Try to match up the lines in the SMTP server log with the email, don't
just look for failures. Open the log in "less" and then search for the
recipient around the correct date and time, then copy/paste all lines
starting with the "connect" through the "disconnect" for that
transaction. There should be two separate sets of log entries, the
first for the delivery from your local client to your SMTP server, and
then a set for the delivery from your SMTP server to the recipient's MX.
Here's a sample from my SMTP server (emails and IPs obfuscated)
Transaction log from localhost to SMTP server
